Black Hole Emits a 1,000-Light-Year-Wide Gas Bubble 145
PhrostyMcByte writes "12 million light-years away, in the outer spiral of galaxy NGC 7793, a bubble of hot gas approximately 1,000 light-years in diameter can be found shooting out of a black hole — one of the most powerful jets of energy ever seen. (Abstract available at Nature.) The bubble has been growing for approximately 200,000 years, and is expanding at around 1,000,000 kilometers per hour."

When Mistakes Improve Performance 222
jd and other readers pointed out BBC coverage of research into "stochastic" CPUs that allow communication errors in order to reap benefits in performance and power usage. "Professor Rakesh Kumar at the University of Illinois has produced research showing that allowing communication errors between microprocessor components and then making the software more robust will actually result in chips that are faster and yet require less power. His argument is that at the current scale, errors in transmission occur anyway and that the efforts of chip manufacturers to hide these to create the illusion of perfect reliability simply introduces a lot of unnecessary expense, demands excessive power, and deoptimises the design. He favors a new architecture, that he calls the 'stochastic processor,' which is designed to handle data corruption and error recovery gracefully. He believes he has shown such a design would work and that it would permit Moore's Law to continue to operate into the foreseeable future. However, this is not the first time someone has tried to fundamentally revolutionize the CPU. The Transputer, the AMULET, the FM8501, the iWARP, and the Crusoe were all supposed to be game-changers but died cold, lonely deaths instead — and those were far closer to design philosophies programmers are currently familiar with. Modern software simply isn't written with the level of reliability the stochastic processor requires (and many software packages are too big and too complex to port), and the volume of available software frequently makes or breaks new designs. Will this be 'interesting but dead-end' research, or will Professor Kumar pull off a CPU architectural revolution really not seen since the microprocessor was designed?"
World's Smallest Superconductor Discovered 72
arcticstoat writes "One of the barriers to the development of nanoscale electronics has potentially been eliminated, as scientists have discovered the world's smallest superconductor. Made up of four pairs of molecules, and measuring just 0.87nm, the superconductor could potentially be used as a nanoscale interconnect in electronic devices, but without the heat and power dissipation problems associated with standard metal conductors."

Dying Man Shares Unseen Challenger Video 266
longacre writes "An amateur video of the 1986 Space Shuttle Challenger explosion has been made public for the first time. The Florida man who filmed it from his front yard on his new Betamax camcorder turned the tape over to an educational organization a week before he died this past December. The Space Exploration Archive has since published the video into the public domain in time for the 24th anniversary of the catastrophe. Despite being shot from about 70 miles from Cape Canaveral, the shuttle and the explosion can be seen quite clearly. It is unclear why he never shared the footage with NASA or the media. NASA officials say they were not aware of the video, but are interested in examining it now that it has been made available."
A Hyper-Velocity Impact In the Asteroid Belt? 114
astroengine writes "Astronomers have spotted something rather odd in the asteroid belt. It looks like a comet, but it's got a circular orbit, similar to an asteroid. Whether it's an asteroid or a comet, it has a long, comet-like tail, suggesting something is being vented into space. Some experts think it could be a very rare comet/asteroid hybrid being heated by the sun, but there's an even more exciting possibility: It could be the first ever observation of two asteroids colliding in the asteroid belt."
Obama Appointee Sunstein Favors Infiltrating Online Groups 689
megamerican writes "President Barack Obama's appointee to head the Office of Information and Regulatory Affairs advocated in a recent paper the 'cognitive infiltration' of groups that advocate 'conspiracy theories' like the ones surrounding 9/11 via 'chat rooms, online social networks, or even real-space groups and attempt to undermine' those groups. Sunstein admits that 'some conspiracy theories, under our definition, have turned out to be true' Sunstein has also recently advocated banning websites which post 'right-wing rumors' and bringing back the Fairness Doctrine. You can find a PDF of his paper here. For decades (1956-1971), the FBI under COINTELPRO focused on disrupting, marginalizing and neutralizing political dissidents, most notably the Black Panthers. More recently CENTCOM announced it would be engaging bloggers 'who are posting inaccurate or untrue information, as well as bloggers who are posting incomplete information.' In January 2009 the USAF released a flow-chart for 'counter-bloggers' to 'counter the people out there in the blogosphere who have negative opinions about the US government and the Air Force.'"
94 New Species Described By CA Academy of Sciences 52
An anonymous reader writes "Researchers at the California Academy of Sciences traversed four continents and two oceans to uncover 94 new species in 2009, proving that while sometimes in this digital age the world can feel like a small place, much of it has yet to be explored. Among the 94 discoveries were 65 arthropods, 14 plants, 8 fishes, 5 sea slugs, one coral, and one fossil mammal. Why does it matter? As Dr. David Mindell, Dean of Science and Research Collections at the Academy, explained, 'Humans rely on healthy ecosystems, made up of organisms and their environments. Creating a comprehensive inventory of life on our planet is critical for understanding and managing resources. Yet a great many life-forms remain to be discovered and described.'"
Nearby "Super Earth" May Have Atmosphere 7
Luminary Crush writes "Astronomers announced that they have discovered a 'super-Earth' which seems to have an atmosphere orbiting a red dwarf star 40 light-years from Earth. They found the distant planet with a small fleet of ground-based telescopes no larger than those many amateur astronomers have in their backyards. Although the super-Earth is too hot to sustain life, the discovery shows that current, ground-based technologies are capable of finding almost-Earth-sized planets in warm, life-friendly orbits."
